How can I make a png image with an alpha mask shadless, meaning the image, which I want to use it as a background, won't be affected (washed out) by the lights in the scene?
I am currently using Blender 2.91. From tutorials, in older version of Blender, there was a shadless option somewhere in the material properties but I can not find it in my current version of Blender.
Simple example is provided in the screenshot below.
